Is an Allergy Shot Harmful?

Allergy shots help combat indoor and outdoor allergies, as well as asthma . According to familydoctor.org, allergy shots are safe for the most part. However, there are certain types of reactions you may experience, some of which can be life-threatening.

  1. Function

    • Allergy shots, also referred to as allergen immunotherapy, are administered to patients who do not find relief from other medication sources. They essentially help your body build long-term immunity against the type of allergens you are the most sensitive to, such as pollen and mold. According to familydoctor.org, allergy shots are administered on a regular basis for up to five years.

    Skin Reactions

    • Skin reactions may develop around the injection site. According to the American Academy of Allergy Asthma and Immunology (AAAAI), skin reactions to allergy shots are common. They can develop immediately, or within hours. The reaction itself is a red and raised bump. According to Mayo Clinic, skin reactions usually go away within eight hours of receiving the allergy shot.

    Systemic Reactions

    • Systemic reactions to allergy shots cause symptoms such as chest tightness, excessive sneezing, hives, nasal congestion, throat swelling and wheezing. Call your doctor immediately if you experience these reactions. If you continuously develop reactions, your doctor may require that you remain at the office for thirty minutes after each shot so that he can administer something to fight the reaction if one should develop, according to the AAAAI.

    Anaphylaxis

    • Anaphylaxis is a rare and life-threatening condition caused by allergy shots in which your body goes into shock. Symptoms include breathing troubles and a sudden drop in blood pressure. According to familydoctor.org, you are more likely to experience anaphylaxis if you do not receive allergy shots on a regular basis . If you suspect you have anaphylaxis, go to the emergency room.

    Warning

    • Familydoctor.org does not recommend that you take allergy shots if you have heart disease, severe asthma, or if you take beta-blockers for a heart condition. The website also advises against administering allergy shots to children under the age of five and pregnant women. There may be an exception if you were taking allergy shots before you became pregnant, but discuss this with your doctor. Also, Mayo Clinic states that allergy shots are not effective against food allergies.
